Air Quality <br /> G.I. Landfill equipment and earth-moving activities (a) Water the working face,excavation area,and Less than Significant <br /> on-site would generate fugitive dust. storage piles frequently,adding a dust palliative <br /> (SIGNIFICANT) (a non-toxic chemical suppressant,such as <br /> magnesium chloride(MgC12)that attracts water <br /> molecules from the air),thereby keeping the <br /> surface'wet for a longer period`Regarding the <br /> use of water,a balance must�be made between <br /> dust control and the generation of additional <br /> leachate. The landfill operator should monitor <br /> dust levels and levels of leachate generated to <br /> determine when and where water should be <br /> applied. <br /> (b) The project sponsor should seek to minimize the <br /> extent of area exposed to wind erosion. Exposed <br /> surfaces,including stockpiles,should be <br /> vegetated to the extent possible or covered with <br /> dust-protectant material,such as a tarp or plastic <br /> cover,to reduce wind action on them. <br /> (c) Plan and phase construction and closure <br /> operations such that they do not take place <br /> simultaneously on dry windy days. <br /> (d) Design the site filling plan to facilitate screening <br /> of the active face from the prevailing winds, <br /> whenever possible,to minimize the amount of <br /> wind blown dust released from the working face. <br /> S.19 <br />
